The beautiful, venomous lionfish is native to the Indo-Pacific, but back in 1985 it started showing up in a weird place: the east coast of the United States. Today you can find the spiny critters along the eastern seaboard, through the Caribbean, down to Belize, and over to the Azores. That’s bad news since the lionfish often crowds out (or consumes) native species.

So what to do? According to Wikipedia, some places have offered bounties for killing them (but, one hopes, not enough to induce breeding and importing) or have established kill-on-sight policies. Another strategy, as the WaPo reports, is to move them down a notch on the food chain:

Federal officials have joined with chefs, spear fishermen and seafood distributors to launch a bold campaign: Eat lionfish until it no longer exists outside its native habitat.

The genius of this approach is that it harnesses a classic economic pathology–the tragedy of the commons–to serve a greater good. No one has any property rights to these interlopers, so all we need to do is create enough market demand for their tasty flesh. Once that reaches critical mass, we can sit back and watch fishermen and -women overfish the Atlantic lionfish into oblivion. Or so goes the theory.

I wish them good luck–and look forward to seeing Atlantic lionfish on the menu soon. I am skeptical, however, that it will actually work. But if it does, maybe the seafood alliance could then turn their attention to the new Potomac snakeheads?
